When cabin crew do their training, do they get in hired help to sit in the cabin mock-up to be evacuted or use Joe public?
I generally pay attention to the safety demo, but figure that in the heat of the moment trying to find and put on the life jacket, evacuate through the nearest exit, or wonder just how hard I can pull on the O2 mask before it breaks, might leave me a little worse for where.
So why not offer the chance for pax to play their part in crew training? I for one would like to try it one day, just so that if i ever had to do it for real I might be of more use to the crew and those around me, and not just the quivering wreck i guess i would be!
